[Mesa-stable] [PATCH 10/53] st/nine: Fix crash when deleting non-implicit swapchain

[Axel Davy]

The implicit swapchains are destroyed when the device instance is
destroyed. However for non-implicit swapchains, it is not the case,
and the application can have kept an reference on the swapchain
buffers to reuse them.

Fixes problems with battle.net launcher.
